Jim,
I just received a 1969-72 Roberto Clemente U1. I was wondering if you could help me narrow it down to an axact year.

The bat is currently 35.6 ounces and 35.75 inches long. Is there any other information that I can give you to help cross reference with the records to get me down to a specific year?
Thanks for all of your help.
